After trying TypeWiz on several different projects, I find it useful to have a CLI tool that will be able to perform the following tasks:

1. instrument - in case of a custom configuration not supported by one of our plugins. One such example is rtf.js - see @zoehneto's comment explaining why it is needed.
2. apply-types - for applying the collected types to the source code, e.g. in typewiz-webpack
3. type-coverage - print the percentage of type coverage (can also be used to enforce specific coverage target in CI), see feat: calculate type coverage #48

I am thinking about renaming the core API of typewiz to typewiz-core, and then using typewiz package to the CLI, so as a user you just install typewiz and can use it (most users shouldn't care about the API part too much).

I'd love to hear user thoughts about this!
